The sad fate of the owner of a biography of Rabbi Akiva Eger.

I was curious. Who was Hermann Scheftelowitz, teacher and cantor in Cosel? I couldn't find out much, but I did learn from this site that he was born in 1882 and died a WWI soldier in 1917. His name appears in the 1932 book Die jüdischen Gefallenen des deutschen Heeres.
